is it possible to either share or allow someone that doesn’t have a plex account to view my movies???
No, they need to have an account. It does not need to be a Plex Pass, it can be a free one.
(I guess I mis-spoke, you could give them your user/password but this would not be the best solution for many reasons.)
See Server Sharing, it outlines the steps needed to get it done
